Groundwater pollution - Wikipedia
Groundwater pollution - Wikipedia

Groundwater pollution, (also called groundwater contamination) occurs when pollutants are released to the ground and make their way down into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.

What is a pH Neutralization System? | Burt Process

The preferred method for pH, neutralization, of waste streams is by the automatic addition of acid or caustic. The ideal setup is a batch, neutralization, module. A basic batch system includes a treatment tank with a mechanical agitator (mixer), an in-tank pH sensor, an intank level control, metering pumps for acid and caustic injection, an automated drain valve or pump for the effluent, and a control panel.
